He places the compass at M and draws an arc from L to K. He plots point R on the perpendicular line beyond the arc. What triangle did Bob construct with the points M, L, and R? A right triangle because the measure of one angle is 90˚. An obtuse triangle because one angle measures 90˚. A right isosceles triangle because at least two sides are congruent. An acute scalene triangle because all angles measure less than 90˚ and all sides are of different lengths. yes Question 8 (Multiple Choice Worth 2 points) (02.02 MC) The figure below shows the steps Stefan took to construct a scalene triangle. Which step in the construction was not required to construct the scalene triangle? drawing an arc with C as the center drawing an arc that cuts line segment XY plotting more than one point on the arc plotting the point beyond the arc yes Question 9 (Multiple Choice Worth 2 points) (02.02 MC) The figure below shows a partially completed construction of an acute scalene triangle.

Which statement is true? Two angles in the triangle are congruent because the lengths of LN and LM are the same as the radius of the circle on which they lie. Two angles in the triangle are congruent because the third angle measures 90˚. One angle is obtuse because M lies on the perpendicular line. The length of segment LN and the length of segment LM is the same because both are perpendicular to each other. yes Question 11 (Multiple Choice Worth 2 points) (02.03 LC) Point P on the grid represents the position of a camera used by an ecologist to study the behavior of lions.

It is a point where all three medians of a triangle intersect. yes Question 18 (Multiple Choice Worth 2 points) (02.04 MC) Which is the centroid of triangle KLM? Point A, because it is the point of intersection of the medians of the triangle. Point A, because it is the point of intersection of segments from the vertices that are of the same length. Point B, because it is the point of intersection of any two altitudes and a median of the triangle. Point B, because it lies outside the triangle. yes Question 19 (Multiple Choice Worth 2 points) (02.04 MC) Look at triangle PQR in which N is the centroid and M is the orthocenter. Which segment must be 3 inches? Segment SQ Segment NT Segment PM Segment RT yes Question 20 (Multiple Choice Worth 2 points) (02.04 MC) Which statement shows a difference between medians and altitudes of all triangles? An altitude connects the vertex of the triangle to the opposite side dividing the side into equal segments but a median does not. A median divides the vertex of the triangle into two angles of equal measure but an altitude does not. An altitude divides the area of a triangle in equal parts but a median divides it into two parts in which the area of one part is twice the area of the other. A median lies inside a triangle but an altitude can lie outside the triangle. yes Question 21 (Multiple Choice Worth 2 points) (02.05 LC) In which figure is the perpendicular bisector of the acute triangle, triangle KLM shown? yes Question 22 (Multiple Choice Worth 2 points) (02.05 LC) The figure below shows triangle PQR with a circumscribed circle of radius 7 inches.

He is not correct because OU does not bisect any angle. He is correct because OU is perpendicular to the side ZY. yes Question 25 (Multiple Choice Worth 2 points) (02.05 MC) Laura said that the circumcenter of all triangles lies either outside or on a triangle. Which figure disproves Laura’s statement?
